VAPORIZER-HEATING DEVICE.

To all whom it may concern:

Beit known that I, ALDEN E. OSBORN, a

citizen of the UnitedStates, and a resident of the city of New York,borough of the Bronx, in the county and State of New York, have inventeda new and Improved VapOriZer-Heating- Device, of which the following isa full, QlQ211',"21-I1d exact descrip- The invention relates to a novelmeans for heatingthe vaporizers of heat engines using liquid fuels,particularly internal combustion 'enginesand oil fired steam engines.

' In automobilev practice it is,a common disadvantage, particularly incold weather,th a't in starting the engine the vaporizer cannot be made'to work properly sc that delay and inconvenience result. l

My invention "is especially suited .to troubles of this sort, andprovides a means by which the'headlight or other lantern of theautomobilemay be utilized to heat the vaporizer, so that when startingthe machine it is only necessary to light the lamp which will furnishthe'heat necessary for starting the operation of the vaporizer, and ifdesired this heatmay be continuedthroughout the entire operation of themachine.

WVhile the invention is especially adapted -to use on internalcombustion engine-driven automobiles, it may.obviously be used' onsteam-driven automobiles and n other analogous arts.

The invention resides in certain special features of construction andcombinations of parts which will be fully set forth hereinafter andparticularly pointed out in the claims.

leference is to be had to the accompanying drawings which illustrate asan example the preferred embodiment of my invention,

in .which drawingsarrangement in which the carbureter is attached to andforms a part of the lamp; and Fig. 4 isa View showing an arrangement bySpecification of Letters Patent.

which the volatile oil employed as a fuel is heated instead of the air.

Referring especially to Fig. 1, it wil be seen that this view shows bythe broken lines 10 the internal combustion engine of the automobile,and by the broken lines 11 the carbureter thereof. These parts arecovered by the bonnet 12 in the usual manner. I let,

indicates oneof the side lights ofthe machine which .15 mountedalongside of the bonnet as shown. Passing from the heater,-

which willbe hereinafter fully set forth, is

a pipe 15 which is preferably, though not. I

necessarily, of flexible material, and which extendsthrough an opening16in the bonnet of the machine, and is joined to the air inlet of thecarbureter 11. It is clear from the fore oin that the lam l4 inav be.made to s g 1 I perform the double function of illuminating the path ofthe. vehicleand of heating the air as it is delievered to thecarlmreter. This preliminary heating of theair is especially. useful instarting the enginealthough 1t111ay with advantage, especially whenthelatmoshere is humid be carried on continuousl during the operation ofthe engine.

Fig. 2 shows a sectional view of the lamp shown in Fig. 1. This lamp isprovided with a burner, hood, reflector and lens which may be of theusual or any desired: construction. Rising from an opening in the top ofthe hood of the lamp is a chimney tube 17 the top of which is closed bya plate 18 having downwardlyoverhanging edges 18*, Just under said edges18 the chimney 17 is formed with outlet openings 17" for the hot gasespassing from the interior of the hood of the lamp. Below said openingsthe chimney tube 17 is provided exteriorly with an annular apron 19spaced from the outer walls of the chimney Vithin the chimney anair pipe20 is coiled, as shown, the inlet end of this pipe passing through thewalls of the chimney under the apron 19, and the outlet end passingthrough a coupling 21 which joins said tube with the tube 15, beforedescribed and shown in Fig. 1. In this manner the lamp while serving itsusual function of illuminating the path of the vehicle heats the coil 20and as the air is drawn through this coil the heat is taken up by theair which is thus carried to the carbureter in a heated state.

Fig. 3 shows an arrangement in which the carbureter is mounted directlyon the lamp 14*. In this view 22 indicates the float chamber of thecarbureter, and 23 the vaporizer chamber, both of which parts are of theusual construction excepting that the vaporizer chamber is formed wlth anumber of hot air "passages 2&, extending vertically formation ofaproper explosive mixture irrespective of the-weather conditions.

' i If desired, fuel as contradistinguished from air may be heatedpreliminary to vaporization, and in Fig. 4 I have illustrated a meansfor attaining this result. In this view the chimney tube 17 of the. lamp14" isprovided with a coiled pipe 25, one end of which communicates withthe gasolene supi ply and the'other end of which passes to the lene is.led to the carbureter' where it may be readilyvaporized, as will beunderstood.

carbureter, thus heating the gasolene by the heat of the lamp. From thecoil 25 the gaso- Having thus described the preferred form of myinvention, what I claim as new and desire to secure by Letters Patentis:

1. In a motor vehicle, an internal com- I bustion engine, a body orcasing inclosing the same, means outside of said casing for illuminatinthe path of the vehicle and also operating to generate waste heat, andmeans for forming an explosive charge and delivering the same to theengine, said lastmentioned means havin a portion thereof heated by saidilluminating means and util-,

izing said waste heat. t

2. The combination with a vehicle, of a motor operated by a liquid orgaseous fuel,

a lamp for illuminating. the path of the vehicle and operating togenerate waste heat, and means for imparting said waste heat to the fueldelivered to said engine.

3. A motor vehicle, havin and using a liquid fuel, a hood or casing for.said engine and normally concealing the same, a lamp for illuminatingthe pathway ofthe vehicle and disposed outside of and adjacent said hoodor casing, and a conduit for delivering fuel to'said engine, saidconduit having a portion thereof heated bywaste heat from said lampwithout interfering with the illumination causedby the latter and saidconduit extending through said hood or casing to said engine. i Intestimony whereof I have signed my name'to this specification in thepresence of two subscribing witnesses.
